• The Toyota Previa was the automaker’s minivan in the ’90s
• Toyota might bring back the Previa nameplate
• The resurrected Previa might feature electrified powertrains

With its aerodynamic shape and mid-mounted engine, the Toyota Previa minivan remains one of the Japanese automaker’s most daring designs. And it might return with plug-in powertrains.

According to a report in Japan’s Best Car magazine spotted by Forbes, a new Previa is slated for a 2026 launch using the TNGA-K platform that underpins the Toyota Camry, Crown, and RAV4, among others, with the intention of accommodating both plug-in hybrid and all-electric powertrains. A hydrogen fuel-cell powertrain was also reportedly considered but the discarded.

This report, which is based on conversations with an anonymous Toyota source, doesn’t mention the U.S. market. But the fact that the TNGA-K platform is already homologated for use here in so many other models could perhaps give Toyota a head start on making the new Previa U.S.-ready.

Granted, the original Previa wasn’t very successful in the U.S. While it gave Toyota an up-to-date entry in the then-booming minivan segment, sales gradually tapered off from its introduction in 1990 to its discontinuation in 1997. Just 3,780 were sold in that final year, Forbes notes, before the Previa was replaced by the more conventional Toyota Sienna.

The Previa stood out thanks to its rounded exterior, often described as egg-like in period. The new Previa will reportedly feature similar styling, while offering seating for up to seven. If it reaches the U.S., it will be a counterpoint to the Sienna, which is now hybrid-only, but still more conservative in design.

Among U.S.-market minivans, all but the Honda Odyssey have switched to hybrid powertrains. The Chrysler Pacifica Hybrid has been a plug-in hybrid for years and as we’ve seen, can go more than 30 miles without the engine.

For the U.S., the Volkswagen ID.Buzz is the first time the minivan—or passenger van—has gone all-electric. But it might not be alone soon. Kia has teased another quirky possibility in the PV5, one of a series of electric vans based on an extremely modular architecture. And an all-electric Chrysler minivan is in the works—potentially as soon as 2027.

The 2023-2024 Ford Lightning electric pickup truck is being recalled for a loose nut that can result in a loss of directional control, the NHTSA disclosed Monday. The issue stems from the wrong torque being applied to a nut on the front suspension during assembly. The suspect nut on the ball joint connects the front upper control arm to the…

Kia is recalling 22,883 EV9 electric SUVs because they may be missing mounting bolts for their second- and third row-seats.

The EV9 arrived in the U.S. as a 2024 model and is currently being sold here as a 2025 model. The recall includes a mix of vehicles from both model years that may have left the factory with missing seat bolts due to an error by an assembly-line worker, Kia told the NHTSA. All of the affected vehicles were assembled in South Korea; Kia began building EV9s at its U.S. plant in June, but has only produced small numbers of the SUVs there.

Without these mounting bolts, seats may not be able to properly restrain occupants in the event of crash, increasing the risk of injury, the safety agency said. Owners may also notice ratting or looseness of the seats if bolts are missing.

Kia estimates that just 1% of the recalled vehicles are missing the bolts in question, and told the NHTSA that it is not aware of any crashes, injuries, or fatalities related to this issue, which was discovered during a quality-control inspection.

Dealers will inspect the seats and replace any missing bolts free of charge. Kia plans to mail owner notification letters Jan. 24, 2025. In the meantime, owners can contact Kia customer service at 1-800-333-4542 for more information. Kia’s reference number for this recall is SC329.

This recall follows two in October. One addressed a remote parking system issue in 12,400 vehicles from the 2024 model year equipped with that feature. The other addresses a software issue in both 2024 and 2025 models that could cause digital instrument clusters to fail.

General Motors is investigating a new way of configuring prismatic battery cells to improve cooling characteristics.

A patent filing from the automaker published by the United States Patent and Trademark Office (USPTO), dated Dec. 26, 2024 but originally filed by GM Jun. 23, 2023, details stacking of layers in an inverted “U” shape, as opposed to the rolled or stacked layers used in current prismatic cells.

This format creates higher thermal conductivity in the horizontal direction in the upper part of the cell for better heat dissipation, as well as in the vertical direction near the bottom of the cell, potentially increasing the effectiveness of cooling systems when they’re installed in a pack, GM claims.

The inverted “U” stack also increases thermal delay time within the cell, causing heat to spread more slowly, according to the filing. Even if the cell overheats, the peak temperature should thus stay lower and potentially be more contained, GM claims, adding that this allows for a thermal response barrier that’s 50% thinner.

That could in future cell designs help reduce cell size, or boost energy density by cramming more active material into that space. And to tease out a greater advantage, pack size might also be smaller due to those reduced cooling needs. 

But the cell format proposed here is also a more complex shape that could present manufacturing challenges, which might explain why the big battery manufacturers haven’t tried it yet.

General Motors inverted

GM already appears to be on a path to use pouch, cylindrical, and prismatic cell formats, all at once, in its production EVs, and it’s emphasized that flexibility. It’s also considered some odd cell shapes in previously filed patents, also with an eye toward improved cooling.

Tesla, Lucid, and Rivian have all chosen to emphasize cylindrical cells—with apparent advantages in range and efficiency. BMW is also set to use cylindrical cells in its next-generation Neue Klasse EVs, the first of which recently entered pre-production ahead of a planned 2025 debut, with promises of substantially increased energy density.

Ford is following other automakers in developing a steer-by-wire system, a recently discovered patent filing shows. The filing in question was published by the United States Patent and Trademark Office (USPTO) Nov. 19, 2024, but was submitted by Ford just over two years earlier, on Nov. 14, 2022. But it deals not with steer-by-wire as a concept…

General Motors is following a handful of other automakers and battery firms in developing mixed-chemistry battery packs for electric vehicles.

GM laid out its version of this concept in a patent filing published by the United States Patent and Trademark Office (USPTO) Nov. 28, 2024. In that document, which was first filed by GM Aug. 2, 2023, the automaker discusses combining nickel manganese cobalt (NCM) with lithium iron phosphate (LFP) or other similar chemistries.

The two chemistries would be split into discreet modules, potentially with different usable capacities, according to the filing. A controller would monitor factors such as temperature and state of charge, and potentially bypass one chemistry or another in a given situation.

A mixed-chemistry pack could balance performance and cost by combining cheaper LFP battery cells with NCM cells, which offer higher power and energy density, GM notes in the filing. Two different chemistries can lead to a charge imbalance that reduce the usable capacity of a battery pack, GM adds, but the automaker hopes ability to bypass one set of cells while charging another will address that.

Certain chemistries can also be charged faster, which could enable smaller battery packs and counteract current pack inflation, which adds cost and weight, consumes more raw materials, and in the real world still often leads to longer charging times once that added charge is exhausted. Combining some of these specialized cells with slower-charging commodity cells could help make EVs more practical.

Other companies are working on mixed-chemistry battery packs. CATL recently announced one aimed at bringing faster charging to plug-in hybrids, and U.S. startup Our Next Energy (ONE) showed in 2022 how it could use mixed-chemistry tech to extract 600 miles of range from a BMW iX—nearly doubling its EPA range. Mercedes-Benz has also developed hardware that could lay the groundwork for mixed cell types.
